WILLIAM CORBBIDGE, OF BURY, ENGLAND.

GAS-FITTING.

Specification of Letters Patent.

Patented Nov. 29, 1910.

Application filed. January 15, 1907. Serial No. 352,338.

To all whom it may concern:

Be it known that I, WILLIAM GORBRIDGE, a subject of the King of Great Britain and Ireland, and resident of Bury, in the county of Lancaster, England, inspector of plumbers work, have invented certain new and useful Improvements in Gas-Fittings, of which the following is a specification.

My invention relates to improvements in gas fittings for incandescent mantles.

My object is to provide an improved arrangement or combination of parts designed to absorb any vibratory shocks and prevent their transference to the mantle. Means have already been suggested to attain this object. Gas has been supplied to an incandescent burner by a flexible tube and the burner has been supported by a spring or springs. Gas has also been supplied to an incandescent burner by a metallic tube of small size coiled in a spiral form.

My invention relates to improvements on these earlier devices and its essential feature consists in forming the gas fitting which supports the incandescent burner wholly or partly of flexible tubing within or upon the surface of which a spring wire is secured the wire being so shaped that a resilient tubular support is given to the burner. I may, if desired, secure that end of the flexible tube which is connected to the gas supply pipe to a swivel or other device readily enabling the tension of the spring wire to be adjusted to the weight of the burner fitting.

My invention will be fully described with reference to the accompanying drawings in which Figure 1 is a side elevation, partly in section, of a wall bracket and flexible tube fltting arranged in accordance with my invention, Fig. 2 is a similar view showing the connection of the flexible tube with a wall bracket suspension pipe or rod and a base or stand, Fig. 3 is a plan view of a segment of a supporting bracket, Fig. 4t is a side elevation in part of the bracket tube show ing the application of the spring wire on the outside of the tubing.

In carrying out my invention I employ a projecting gas tube a of a suitable character and supported in any suitable way from a ceiling 6, wall 0 or base d as in Fig. 2, or wall a as in Fig. 1. To the external end of the tube a in Fig. 1 I secure one end of the flexible tube 6 which is by preference a flexible metallic tube and which has inserted in the bore as already described a spring wire f, the

other end of the flexible tube being connected to a second portion of gas tube 9 or to a nipple to the exterior end of which is connected or in which is inserted the gas burner or burner fittings carrying the mantle. The flexible tube may be bent into any suitable resilient form such as a coil as indicated in Figs. 1 and 2 and the spring f employed is of such a strength as to be capable of resiliently supporting the gas burner and fittings in the positions required. For burners of different weights spring Wires of diiferent strength may be used but the same spring wire may be used for burners of considerably varying weight or means are provided for varying the tension of the spring wire. One simple way of varying the tension of the spring wire is to connect the supply end of the flexible tube to a swivel joint such as used in connecting ordinary rigid pieces of gas tube together. A swivel joint such as I have referred to is indicated in plan in Fig. 3. Here 2' shows the plug which is tapered to fit into the end 9' forming part of orattached to the rigid gas tube. It will thus be seen that by raising or lowering the pivoted end of the bracket the same may be adjusted for different fittings and in this way I can deal with any reasonable diflerence in weight of the burner fittings and yet retain the parts in proper position and at the same time not interfere with the flexibility of the flexible tube.

The spring wire if suitably tempered may be bent to the shape required prior to or after its insertion in the tube. The ends of the spring may be left loose in the tube or rigidly connected at the gas supply or burner end or at both ends. The spring may also be arranged on the outside of the tube in stead of inside it as shown in Fig. 4 of the drawings, in which case it is secured to the tube by metallic clips, wire, or other suitable means as indicated at 70.

The whole of the gas fittings may be made of the flexible tube as in Fig. 1 or part flexible tube a and part ordinary drawn tube Z as in Fig. 2 the connection of the flexible tube and rigid tube being by means of nipples m or by other simple means.

By the arrangements described I provide a neat and effective device of an adjustable character and one which entirely prevents the transference of vibratory shocks to the mantle. And, while I have described a swivel as the adjusting means,

'mantle by I and allowi g th tube to ris at ex ern l end I may portion of the tube by a hook as in Fig. 2 to hold the parts rigid until the chimney and globe are placed in position again.

What I claim as my invention and desire to proteot by Letters Patent is In a bracket, the combination with a sup- I may employ during such removal secure the 7 end to the main small chain and my hand in the ply pipe havin a rigid connection, a flexible tube pivota 1y connected thereto, a wire spring of'a determined configuration resiliently carrying said flexible tube, and means for adjusting the Whole in different relative posit ons Without affecting the configuration thereof.

In testimony whereof I have hereunto set presence of two Witnesses. IVILLIAM GORBRIDGE,
